Each of the tillers or webvmembers 3 may be of any desired construction, but preferably they are pressed plates of general pan shape as shown, having integral flanges on both ends and top and bottomedges. The. central brace 4 is also composed" of-pressed. plates of generalpan shape having, integral flanges on their'four edges, said flanges being- I dented inwardly at the corners in order to give a neat tit againstthe flanges of the center sills. The center brace and web memhers are composed of two pressed .mernbers arranged in pairs and placed back to back,

rivets passingthrough the flal'lges'at the ends of the center braces and at the inner ends of the side webs, and the webs of the center sills. Each bolster is provided with a bottom transverse connecting member 5, shown as a plate extending-from side. to' side of the car and of greater width at its middle than at its ends. This plate is riveted to the bottom flanges of. the web tillers and center braces. The bolster has no cover plate, but the tfloor plates 6 are riveted to the tepjilanges-ofthe web tillers and center braces, anditherefore constitute a top' coverplate or connecting member.

The car is provided with a plattorm frame consisting of the projecting ends of the een ter sills 1 and platform beams 10, which extend inwardly as far as the body bolster, being secured to the web of the latter by suitable connecting pieces.
